Composing Configurations with JQ on April 26, 2016
When managing configurations for services there are often variables which need to be changed depending on the environment or use case. Different tools deal with that sort of parameterization slightly differently. For example… AWS CloudFormation - stack templates have a high level Parameter type which can contain user-supplied values. There are built-in functions to concatenate and do some other primitive transformations. BOSH - manifests are actually an ERB template, allowing for dynamic inclusion of environment variables, file contents, settings from configuration files, or complicated logic.
